The oceans are full of plastic. Now, research finds that even barnacles are feeling the consequences.

A third of barnacles caught in the North Pacific gyre, a region of the ocean notoriously littered with scraps of plastic, have microfragments of the plastic material in their digestive systems at a given time, a new study finds. Researchers aren't sure whether ingesting the non-food harms the barnacles, but it could crowd out real nutrition.
